   The type with a narrow-edged plastic piston that slightly expands the   
   bore where it contacts seems OK with petroleum products like grease.   
      
   Hydraulic seals are made of Buna-N or nitrile rubber. Viton should also   
   work.   
      
   -----------------   
      
      These are glass tube assemblies with gaskets . I have some HDPE I   
   could make a piston from but I'd have to have 2 thin edges so it would   
   be able to suck oil up into the syringe . I think I'll stick with the   
   o-ring design . I have metric and SAE assortments - I'd have to go out   
   to the shop to see what they're made of and that ain't happenin' tonight .   
      This morning I pulled the bed off my truck so I could do some   
   finish-up work on the exhaust (finish some welding and fab/install a   
   crossover pipe) and so I can remove the axle to take to the shop . I   
   have a guy that's done gear set replacements that's going to do mine .   
   He got a bunch of Sioux valve/guide/seat tooling in exchange for the   
   axle work . It's going in as a 2.73:1 regular differential . It's coming   
   home with 3.42's and an Eaton style posi locker .   
      And my back hurts . After 4 shots of 99 proof whiskey it still hurts   
   but now I don't care .
